The prolific screenwriter-director also used the TCA platform to stress the authenticity of Roadies. Multiple times during the panel, he noted that several characters or plot points included in the series are based on true stories -- and legends -- that exist within the music industry. A story in the pilot about a pianist who flips out when there are fingerprints on his piano, he said, is based on Freddie Mercury, while co-star Peter Cambor's guitar tech is based on Elvis Costello.

You have a fake British accent on the show that everyone seems to know is not real, which I’m sure they show will explore. Did you try to learn a good British accent?

When I auditioned for the part, the idea was that it would be the way people like Madonna have taken on a British accent in the past. Milo’s backstory is that he had been on tour with Elvis Costello and is someone who has aspirations to be out there performing himself. He’s a chameleon who takes on personas. For me, I had to really try, like “I’m British now.” I really worked on it to try and make it as real as possible knowing that it would be just OK.
